DUMPlNG-CART.

SPECIFICATION formingpart of Letters Patent No. 477,702, dated June 28, 1892. Application filed November 10, 1891. Serial No. 411,427. (No model.)

To all whom it may concern.-

Be it known that I, LEoNnARD Roman- HAUSEN, a resident of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Dumping-Carts, of which the following is a specification.

My invention has reference to dumpingments, which are fully set forth in the following specification and in the accompanying drawings, which form a part thereof.

My invention comprehends improvements upon that class of wagons in which the body part is caused to rise above the running-gea r or truck and at the same time be tilted to the requisite inclination to insure the proper dis-- charge of the coal or other contents. Heretofore this has been accomplished by use of parallel links or arms connecting the body part with the i-unninggear. In some cases the links or arms have been loosely connected with the body part or running-gear, and in most cases the power has been applied to one set of the hinge arms or links. My present improvement specifically refers to means for insuring the proper inclination of the body for properly discharging the coal and without the necessity of fully raising said body part when the elevation for the discharge does not require it. In some wagons the body part must be first raised to its full height for discharging the coal at an elevation from the running-gear, even When an intermediate or less elevation is desired. This is objectionable, as it puts needless labor upon the operator, since he must first fully raise the entire load of coal and then after adjusting the parts lower it to the desired degree. My present invention overcomes this defect. In many wagons the body part is divided by transverse removable partitions or division-boards, so that a portion ofthe coal may be delivered at one place and the balance at one or more other places. In these wagons, when the coal has been discharged from the rear portion of the wagon, the forward part of the body is heavily loaded and has nothing material in the way of weight to counterbalance it. This causes the front end of the body to drop while discharging the contents of the first partition. In some cases provision is made to overcome this defect in a measure; but nothing prior to myinvention has been found positive and easily managed.

In the drawings, Figure 1 is a sectional side elevation of a dumping-wagon embodying my invention. Fig. 2 is a sectional plan view of the same on line was. Fig. 3 is across-seetion of the same on line y y, and Figs 4 and 5 are side elevations of modified forms of wagons embodying my invention.

A is the running-gear, and consists of the sills supported upon two or more wheels in the ordinary way. I have shown a four-wheel vehicle; but this is not essential.

B is the box-shaped body part for holding the coal orother merchandise, and is provided with the usual gate 6 at the discharge or tail end. A

O are transverse partitions or divisionboards, and are removable, so as to make a number of compartments D E F, when desired. When these are used, the com part7- ment E is emptied first, then compartment D', and finally compartment F. The body B is supported upon hinge arms or linksG and H, the former being operated by power devices N and chains 0. The power devices shown are a shaft, multiple gear, and a crank. By this means the operator can exert great power. Any other form of power devices may be employed to raise the body above the runninggear. The arms or links G are positively hinged at the bottoms to the running-gear A and at the tops and forward end to the body part near the middle thereof, and preferably somewhat in advance of the center of gravity of the loaded body, so that in rising the forward end will have a tendency to risehigher than the rear end and in many cases before the rear end has left the sills of the runninggear or truck. One of the sets of arms or links is connected with one of the parts A and B by a movable or sliding connection.

In the construction shown in Figs. 1 and 2 the forward arms or links H are hinged positively to the running-gear at the bottom and are connected by a sliding'guide I at their tops with the body. -If the wagon is fully loaded, this construction will insure the forward end of the body being fully raised before the rear end begins to leave the sills of the truck. This construction is old and well known. By its use the forward end of the body has to be fully raised before the rear end can be elevated to any degree. ob ectionable. To overcome this defect, I hinge to the body at K a bar J, having holes L in its lower part. WVhen the front end of the body has been raised to the desired height, the bar is fixed on a stud or pin M on the frame of the truck and locked by a key on. A further movement of the power devices will then elevate the rear end, cutting out the use of the links or arms II and, moving the body on the bar J as a fulcrum. If now the contents of compartment E be dumped, the load in compartments D and F cannot force down the forward end, as indicated in dotted lines, and prevent the automatic discharge of the coal. The bar J thus limits the elevation of the front end of the body and controls the amount of the sliding movement of the link II in the guide I. It also supports the front end of the wagon-body and causes the rear end to be elevated through the operation of the power devices by acting as a stationary fulcrum.

In practice I have found it best to arrange the bar J as well as the upper hinge-points of the links or arms G to the front of the center of gravity of the fully-loaded body, but so that the latter comes to the rear of the center of gravity when the compartment at the rear is first discharged. The particular construction of the adjustable support at the front is immaterial, as is also the means of adjustment. One of the bars J may be on each side of the wagon or only upon one side, as desired.

Referring to Fig. 4, we have the same general construction as that of Figs. 1 and 2,but in place of the guide I on the body the link H has a variable or movable means of connection with the running-gear in a crank h. This accomplishes the same result and is the equivalent, so far as my invention herein set out is concerned, of the sliding connection shown in Figs. 1 and 2. A lever 11 may be employed to oscillate the crank h to vary the inclination of the body before looking the forward end by the bar J, if so desired. In Fig. 5 We have the same construction as that of Fig. 4 with the links or arms I-I placed to the rear of the arms or links Gr.

I do not confine myself to any details of construction, as all of these constructions shown are types of the same general invention, and the general result accomplished by the employment of my invention is the same.

This is The details may therefore be modified without departing from the principles of the inventiou.

, Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a dumping-wagon, the combination, with the running-gear and body part, of links or arms positively connected at one end with the running-gear and at the other end with the body part, links or arms positively con: nected at one end with one of said parts and at the other end with the other part by a movable connection, power devices for moving one or more of the links or arms, and an adjustable supporting and elevating bar between the forward end of the body part and the running-gear, whereby said supportingbar when adjusted limits the extent of the elevation of the forward part of the body, supports said forward part, and causes the elevation of the rear of the body.

2. In a dumping-wagon, the combination,

with the running-gear and body part, of elevating-arms positively connected with the running-gear and body part, power devices to operate said elevating-arms, connecting-arms positively connected at one end with the runhing-gear and having a sliding connection at the other end with the body part, and a supporting and elevating bar pivotally connected at one end with the body part and having an adjustable connection with the running-gear at its other end, whereby said supporting-bar when adjusted controls the amount of sliding movement of the connecting-arms and limits the elevation of the wagon-body.

3. In a dumping-wagon, the combination, with the running-gear and wagon-body, of the elevating-arms G, connected with the runhing-gear and wagon-body, the forward connecting-arms I-l, pivotally connected with the running-gear, the slotted plate I on the wagonbody, in which the upper ends of the connecting-arms II are received and free to slide, and the supporting-bar J, pivotally connected at one end to the forward part of the wagonbody and at the other end with an adjustable connection to the forward end of the runninggear. 1

In testimony of which invention I have hereunto set my hand.
